Removing dimples on remington 870 magazine tube.
I just got a new remington 870 turkey express.
I wanted to install a magazine tube extension. I tried the socket method and it work with a 16mm socket. You should oil up the tube and socket well and remove the shell follower. Insert the socket that fits in the tube but does not pass by the dimples. Slightly hammer it in. as it pops out the dimples ,it gets stuck and you cannot remove it. (This is Good it means the dimples are pushed out.) Take all the other sockets in you socket set smaller than the on you used and load them in the magazine tube like they were shells. Take a hammer and a screw driver and tap the exposed sockets inside the reciever. The stuck socket will shoot out the magazine tube. Dump all the other sockets out of the tube and you are good to go. NO drill, No drimel tool no bluing or parkerizing rubbed off. It worked great for me. Give it a try.

Good going, Super-Dave! I like simple solutions.
One point to ponder, different socket sets have different wall thicknesses -- your 17mm may not work as well as Super-Dave's. |

Just keep trying different ones untill you find the perfect fit.
Try them very gently and make sure you tap it with your hammer gently.

It worked fine for me. The dimples poped out and the follower goes through easily.

Perhaps you need a socket exactly like Super-Dave's. Super-Dave Can you be micrometer-man on the OD of your famous 17mm, and post the dimension. |

I tried 3 different styles of Craftsman sockets 17mm was too big 16mm was too small. I also tried inch based sizes. Let us know what brand of socket you used. I have some other assorted brands of loose pieces and one of those may work.
Thanks! |

I used the stanley sockets they sell all walmart.
it is like $18.00 for a pack of stanley metric sockets I think I was wrong on my first post I think it was the 16mm stanley socket.

I did it!!
Well I got the dimples out using the socket method and finishing with the Drimmel tool. Smooth as a Baby's But, and it didn't break through (NO HOLES). Does anybody know how to cover the now exposed metal inside the magazine tube due to the drimmel work? I'm just worried about rust. Does anyone have any suggestions? Please let me know, Thanks

Dave I think you are right it looks like a 16MM from my husky set is just about perfect. Good job on the work around.
XM21- I would try a different brand of socket ODs will be different, you are correct any dimple on the inside is a BAD THING must be baby butt smooth for the follower to run properly! davidsldennis - Cold blue with q-tips to cover the shinny parts if you must.

CLP or a thin coat of grease should do the trick. Cold blue isn't much of a corrosion protectant - cold blue in and of itself is a type of controlled corrosion.

PLEASE do not use grease or oil on the inside of your mag tube Grease works like a gasket and will stop up the spring/follower.

I may be confused but I thought that was what the blue and brown process on metal in the white was for?

Yes, bluing pen! I just happen to have lots of q-tips and a big bottle of cold blue.

Wow... I really wish I had read up on here a little more before I bought a dremel tool just for that!

Now, don't get me wrong, I'm not complaining, but, why are there no dimples on my 870 Express Magnum?
I keep reading about these dimples and wondering how I got so lucky as to not have them on my 870.(WOOHOO!!)

Remington, Thanks to folks complaining and the craziness of having two separate barrel and magazine lines have SEEN THE LIGHT and dropped the infernal plastic retainer for the original detent and nut. Once in a while reality prevails!
Good Luck & Be Safe

Where did you hear that, Scattergun Bob? I just recently posted a thread about my new Wingmaster having the dimpled tube with the plastic retainer. I called Remington and was told that all new Wingmasters are going to come that way. I didn't ask about the Express, but I would imagine it would be the same.
I suppose I should ask, does having the dimpled tube somehow limit my barrel choices? |

I don't understand why Remington even bothers with the dimples. I know they're there as a preventative measure from installing a magazine tube extension, but if its that easy to remove the dimples then why bother?

The Chinese Pardner pumps have the same dimples and plastic retainer, too.

The dimples are there to protect you from yourself! Anyone who needs more than 4 rounds in a shotgun MUST be some kind of psychopath! I am so glad I got into the 870 game before the dimples were dreamed up. Be careful with the socket deal, I have heard of several people ending up with the socket really really stuck inside the tube and damaging the tube trying to hold it while driving the socket out. I think I would just grind the dimples off. I also wouldn't worry too much about the finish inside the tube, the spring and the rims will grind most of that off over time anyway.

sorry to bump a really old thread but I need some help.
I tired this method and the 16mm just fell inside and the 17mm seemed about right so I tried that and now it seems stuck. I am afraid to use to much force and never be able to get it out.
